Peritraumatic Behavior Questionnaire- Observer Rated: Validation of the objective version of a measure for combatrelated peritraumatic stress

AIM: To validate the first third-person-rated measure assessing combat-related peritraumatic stress symptoms and evaluate its psychometric properties and war-zone applicability.METHODS: The valid assessment of peritraumatic symptoms in the theater of military operations represents a significant challenge in combat-related, mental health research, which mainly relies on retrospective, subjective self-report ratings. This longitudinal observational study used data from actively deployed troops to correlate third-person observer ratings of deployment peritraumatic behaviors [Peritraumatic Behavior Questionnaire- Observer Rated(PBQ-OR)] collected on a bimonthly basis with post-deployment(1-wk follow-up) ratings of the previously validated PBQ self-rate version(PBQ-SR), and(3-mo follow-up) clinician assessed and self-report posttraumatic stress disorder(PTSD) symptoms(Clinician Administered PTSD Scale, PTSD Checklist). Cronbach's alpha(α) and correlation coefficients were calculated to assess internal reliability and concurrent validity respectively. RESULTS: Eight hundred and sixty male Marines were included in this study after signing informed consents at pre-deployment(mean age 23.2 ± 2.6 years). Although our findings were limited by an overall sparse return rate of PBQ-OR ratings, the main results indicate satisfactory psychometric properties with good internal consistency for the PBQ-OR(α = 0.88) and high convergent and concurrent validity with 1-wk post-deployment PBQSR ratings and 3-mo posttraumatic stress symptoms. Overall, later PBQ-OR report date was associated with higher correlation between PBQ-OR and postdeployment measures. Kappa analysis between PBQOR and PBQ-SR single items, showed best agreement in questions relating of mortal peril, desire for revenge, and experience of intense physical reactions. Logistic regression demonstrated satisfactory predictive validity of PBQ-OR total score with respect to PTSD caseness(OR = 1.0513; 95%CI: 1.011-1.093; P = 0.02).CONCLUSION: Since no comparable tools have been developed, PBQ-OR could be valuable as real-time screening tool for earlier detection of Service Members at risk.

The 25 - 30 year olds predominated, 52.78%. 100% of soldiers had significant peritraumatic dissociation, of which 94.44% also had significant peritraumatic distress. 100% of the soldiers had manifestations of intrusion, 89% of manifestations of avoidance and 83% of manifestations of hyperexcitation. 88.89% had an index for acute stress including 100% of victims of night assault and vehicle explosion on mine. Conclusion: This study shows a high prevalence of peritraumatic reactions, recognized factors favoring post-traumatic stress disorder, and the interest of their evaluation for medical and psychological help adapted to the victims.
